what is the function of Mid,Fore and Hind brain?
Answers
Answer:
Fore Brain
It is the main thinking part of the brain and controls the voluntary actions. The forebrain processes sensory information that is collected from the various sense organs such as ears, eyes, nose, tongue, skin. It is because of the presence of forebrain, humans are placed at the highest level in the animal chain.
The forebrain consists of the Cerebrum, Thalamus and Hypothalamus.
The cerebrum is the biggest part of the brain. This part we associate with higher brain functions such as thinking and action. It contains the cerebral cortex and other subcortical structures. The cerebral cortex is highly wrinkled and makes the brain very efficient. Now the cerebral cortex again divides into four divisions called lobes. They are:
Frontal lobe –Is associated with parts of speech, reasoning, problem-solving, planning, movement and emotions
Parietal lobe – We associate parietal lobe with recognition, orientation, and perception of stimuli
Occipital lobe – Is responsible for visual processing
Temporal lobe – Finally temporal lobe is associated with memory, speech perception and recognition of auditory stimuli
The cerebrum is divided into two halves by a deep furrow. These halves are the left and right hemispheres. Each side functions slightly different from the other, even though they are symmetrical. So the right hemisphere links to creativity whereas the left hemisphere relates to logic abilities. And Corpus callosum connects the two hemispheres.
Mid Brain
The midbrain connects the forebrain and the hindbrain. It acts as a bridge and transmits signals from hindbrain and forebrain. It is associated with motor control, vision, hearing, temperature regulation, alertness.
Hind Brain
It is the control centre for visceral function.As a result, this part of the brain plays a role in controlling the heart rate, breathing, blood pressure, sleep and waking up functions etc. The hindbrain has three parts, namely – medulla oblongata, pons and cerebellum.
The cerebellum is responsible for maintaining equilibrium, transfer of information, fine adjustments to motor actions, coordinating eye movements etc. Coordination and body balance, posture during walking, riding, standing, swimming, running, are all maintained by the cerebellum.
